AUTOMATIC STOP FOR TALKING-MACHINES.

To all whom it may concern:

Be it known that I, CHARLES H. SWIEGLE, residing at Spokane, in thecounty of Spokane and State of Washington, have invented new and usefulImprovements in Automatic Stops for Talking-Machines, of which thefollowing is a specification.

This invention relates to talking machines and has for its object theprovision of means whereby upon completion of the playing of a diskrecord, mechanism will be actuated for stopping the motor andconsequently the rotation of the turn-table and record.

An important object is the provision of means of this characterincluding a turntable provided with a cut away portion upon which isadapted to be disposed a record of the disk type provided with apartially spiral slot formed as a continuation of the sound grooves ofthe record and through which the stylus is adapted to drop, theturn-table having disposed therebeneath a trip lever adapted forengagement by the stylus and connected with the brake setting mechanismfor stopping rotation of the turn-table.

Another object is the provision of means ofthis character which will besimple and inexpensive in construction, eflicient and automatic inaction, durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed, and illus trated in the accompanying drawing, inwhich- Figure 1 is a plan view of a talking machine having disposed uponthe turn-table thereof a record constructed in accordance with myinvention,

Fig. 2 is a plan view of the turn-table with the record removedtherefrom.

Referring more particularly to the drawing, the numeral 10 designatesthe turn-table of a talking machine of any ordinary or preferred type.This turn-table 10 is provided with a semicircular cut-out portion 11and has disposed therebeneath a lever 12 positioned beneath the cut-outportion 11 and connected by means 13 with the brake setting lever 14 forstopping the rotation of the turn-table.

Adapted for use in connection with a phonograph having its turn-tableconstructed as above described, is a disk 15 Patented Feb. 10, 1920.

over the cut-out portion 11 in the turn-table when in playing position,

In the operation of the devcie it will be seen that when the disk record15 is placed upon the turn-table 11 with the slot 16 disposed over thecut-out portion 11, and the stylus reaches the end of the sound grooveit will drop into and through the slot 16 in the record and into thecut-out portion 11 of the turn-table and will engage the lever 12 andconsequently move the same for shifting the brake lever 14 to itsposition for stopping rotation of the turn-table.

From the foregoing description and a study of the drawing it will beapparent that I have thus provided a very simple and efficient meanswhereby a talking machine will be stopped automatically upon completionof the playing of a record. It will be observed that the record, if adouble 011e, may be provided on both sides with slots at the inner endsof the sound grooves so that the automatic stop will be actuated,regardless of which side of the record is played.

While I have shown and described the preferred embodiment of myinvention, it is of course to be understood that I reserve the right tomake such changes in the form, construction, and arrangement of parts aswill not depart from the spirit of the invention or the scope of thesubjoined claims.

Having thus described my invention, I claim 1. In combination, a talkingmachine turn-table provided adjacent its center with a cut-out portion,alever disposed beneath the turn-table and operatively connected withthe brake lever of the talking machine, said first named leverprojecting beneath said cut-out portion, and a record provided at theinner end of its sound groove with a partially spiral slot adapted to bearranged above said cut-out portion of the turn-table, whereby thestylus of the talking machine will, upon reaching-said slot, passtherethrough and engage said lever whereby to apply the brake.

2. In combination with the turn-table of a talking machine, saidturn-table being provided adjacent its center with an opening, a leverprojecting partially across said opening and operatively connected withthe brake lever of the talking machine, and a record provided adjacentits center with a slot formed as a continuation of the inner end of thesound groove of the record, said slot being adapted to register with thecutout portion of said turn-table whereby upon reaching the end of thesound groove the stylus of the talking machine Will drop through saidslot and said cut-out portion and will engage said lever for moving thebrake lever to its potential position.

8. In combination, a talking machine turn-table provided with a cut-outportion, a lever operatively connected with the brake lever of thetalking machine and disposed beneath said out out portion, and a recordprovided at the inner end of its sound groove with an opening adapted tobe arranged above said cut out portion of the turn-table, the stylus ofthe talking machine entering said opening, at the completion of theplaying of the record, and engaging said lever whereby to apply thebrake.

In testimony whereof I afiix my signature.

CHARLES H. SlVIEGrLE.
